Polyester silica nanocomposite fabrics were prepared by incorporating different concentrations of silica nano particles to the fabric by pad-dry-cure method. The prepared composite fabrics were analyzed in terms of change in their mechanical, structural as well as their functional properties. The surface morphology showed the uniform distribution of silica nano particles on fabric through SEM, ...

This paper presents the results of absorption spectra, fluorescence properties and the effect of solvents on UV-Vis spectra of dye quaternized 4-acetylamino-N-2-aminomethylpyridine-1,8-naphthalimide. The fluorescency of the dye was evaluated and its Stokes shift value was 6140 cm-1 in DMF. The solvatochromism behavior of the novel compound is investigated by studying its spectra in pure organic...

Traditional dyeing usually consumes a significant amount of water and salts, thus causing environmental pollution. Salt-free low-water has become an important research direction in the cotton fabric industry. The non-aqueous media technology, using decamethylcyclopentasiloxane (D5) as medium, achieved energy saving emission reduction this To investigate influence inorganic salts on properties r...

 This paper describes the use of image processing to measure lightness changes of fabric appearance. The lightness changes due to dyeing, washing and exposure to light treatments are studied. These properties are measured by using the changes in the intensity levels of the fabrics image and the L* obtained by a spectrophotometer. For each case, analysis of variance (ANOVA) is carded out and the...

Lawsonia inermis L. (= L. alba Lamk.), belonging to the Lythraceae family, is a very widespread medicinal plant and natural dye in the world. This herb which has interesting dyeing properties was used traditionally for centuries in Asia, in Africa for dyeing hair and painting skin and nails. Since 1890, it has been widely distributed to Europe and nowadays available in worldwide market as ingre...

The thermomechanical and dynamic mechanical properties of films and fibres in vapour laden atmospheres and simulated dye baths were investigated in order to understand their processing behaviour. Acetone and water vapour acted as plasticisers for cellulose acetate film. 2-phenoxyethanol was found to penetrate poly(ethylene terephthalate) film above its glass transition temperature and consequen...

Attempts were made to modify polypropylene fibers by melt blending with polyethylene terephthalate in order to enhance the dyeability of the resultant fiber. Five blends of polypropylene/polyethylene terephthalate/compatibilizer were prepared and subsequently spun into fibers. Three disperse dyes were used to dye such modified fibers at boiling and 130 °C. The dyeing performance of the blend fi...

Microwave dyeing was carried out under a variety of conditions in terms of the power and time of a microwave to investigate the effects of microwaving on the dyeability of acrylic fibers. It was found that the dyeability of acrylic fibers were significantly improved under microwave irradiation caused by the increased adsorption of the dye into fibers due to the local over heating and an amplifi...

In order to facilely achieve pretreatment and salt-free dyeing of greige knitted cotton fabrics, a combinative scouring, bleaching, and cationization pretreatment of the fabrics is designed in this study. The fabrics are first treated in a bath containing commercial scouring and bleaching agents, and then glycidyltrimethylammonium chloride (GTA) is directly added into the bath to achieve cation...
